Methane Gas from Sewage Works can now be burnt with the all new Waste Gas Burner supplied by SAUBATECH. The MACROblaze 300W Waste Gas Burner consists of a burner head mounted on a vertical column, which protrudes upwards from a pedestal.
Pilot Gas is fed through a small flame arrestor, a solenoid valve and 15 n/b stainless steel pipe to a toroidal chamber near the top of the column. A ring of replaceable nozzles emit the gas in vertical jets where it mixes with air under the pilot ring before passing upwards and burning in a circle of pilot flames. “The size of the nozzle jets can be changed to suit the size of pilot flame required,” says Peter Thieme of SAFURNCO.
The main gas supply reaches the burner head via the column. A high chrome cast iron turbulator across the top of the column disperses most of the gas sideways and imparts a rotational movement.
Gas enters the column base via a tee piece and passes downwards around the outside of a concentric inner pipe. The inner pipe ends short of the base, allowing the gas to turn inwards and enter the bottom of the inner pipe which forms the column. Flow of the gas is controlled by water in the base of the column. The existence of flame in the burner head is monitored by thermocouple.
A water tank, divided into two compartments, is built into the pedestal. One of the compartments, the water supply tank, is fitted with a ball-cock on the water inlet pipe to keep the water in the supply tank at a constant level.
Water flow from the supply tank to the base of the column is controlled by normally open solenoid valve. When the valve is not energised, water from the tank flows into the column, covers the bottom end of the inner pipe and prevents gas from escaping upwards to the burner head.
